The key to deriving an estimate on the behavior of the third order structure function (REF ) is the so-called Kármán–Howarth–Monin (KHM) relation [1]} that describes the evolution of the second correlation marginal. Similar relations have been derived before for various settings (stochastic, forced, etc.), see [2]}, [3]}, [1]}, [5]}, [6]}, [7]}, [8]}. For statistical solutions we derive:
